I built WhatsBuzzing - http://heyjimmy.net/whatsbuzzing<p>Its use is two-fold:<p>1) General users on Facebook can login and see the top 40 trending topics on their Newsfeed, through statuses and comments.<p>2) Data is collected and access is going to be sold to third parties like advertisers, designers, and media companies. With this data they can get a real feel for what people are thinking about topics like, the World Cup, or a new movie, Coca-Cola, etc.<p>I just need to get users now :)
